Specifying a Time-to-Live Value
By default, RIP inserts a time-to-live (TTL) value of 1 hop into each outbound
routing update. Setting a TTL of 1 prevents RIP updates from inadvertently
getting off the local network. Increasing the TTL introduces the risk of the update
getting off the local network and being forwarded around the network.
Certain RIP implementations ignore packets with a TTL value of 1 hop. Use this
parameter to provide interoperability with such implementations.
You can use the BCC or Site Manager to specify a TTL value greater than 1.
Using the BCC
Navigate to a RIP interface-specific prompt and enter
time-to-live
hops
hops is the time-to-live value (expressed as the number of hops) that RIP inserts in
each outbound update.
For example, the following command causes RIP to insert a TTL value of 2 in
each outbound update.
rip/2.2.2.2# time-to-live 2
rip/2.2.2.2#
Note: For compatibility with routers running Version 8.10 or earlier, disable
this feature. Pre-Version 9.00 implementations of RIP do not support triggered
updates.
